Giant Gating Tunability of Optical Refractive Index in Transition Metal Dichalcogenide Monolayers
Yiling Yu, Yifei Yu, Lujun Huang +3
We report that the refractive index of transition metal dichacolgenide (TMDC) monolayers, such as MoS2, WS2, and WSe2, can be substantially tuned by > 60% in the imaginary part and…

Fundamental Limits of Exciton-Exciton Annihilation for Light Emission in Transition Metal Dichalcogenide Monolayers
Yiling Yu, Yifei Yu, Chao Xu +3
We quantitatively illustrate the fundamental limit that exciton-exciton annihilation (EEA) may impose to the light emission of monolayer transition metal dichalcogenide (TMDC) mate…
